漠河地区潮满林场768高地银铅矿床成矿流体特征及其成因
Metallogenic fluid characteristic and genesis of silver lead deposit in 768 highland of Chaoman forest farm in Mohe
摘要
Abstract
This paper is intended to investigate the metallogenic fluid characteristic and genesis of silver lead deposit in 768 highland of Chaoman forest farm in Mohe region,Heilongjiang Province.The study works by fluid inclusion microthermometry together with the geological characteristics of the deposit.The results show that this deposit occurs in Late Carboniferous granite closely related to the early Creta-ceous intermediate-acid dyke.It can be divided into three stages of pyrite-quartz,polymetallic sulfide-quartz and less sulfide-carbonate.The deposit is mainly characterized by medium-low temperature miner-alization and alteration,including chalcopyrite,galena,sphalerite,pyrite,silicification,sericite miner-alization and so on.The fluid inclusion type of the deposit is only gas-liquid two-phase inclusions which is the H2 O-NaCl hydrothermal solution with the medium-low temperature and medium-low salinity.Based on the comprehensive analysis,the mineralization is directly related to the early Cretaceous intermediate-acid intrusive rocks,and the deposit belongs to the medium-low temperature magmatic hydrothermal vein type.关键词
